You likely think about towering mountains, steep ravines, and rushing rivers when you think about the Montana landscape. There’s no denying that Montana has some of the most beautiful scenery. However, besides the jagged mountains, Montana has some other exciting features below the earth’s surface — caves. 

Join us as we explore caves in Montana. It might be enough to get you to book that trip you’ve been considering. Let’s go spelunking! 

Are There Caves in Montana?

Yes, there are caves in Montana. It’s home to over 300 known caves. Most of them are “wild caves” versus tourist caves.

They typically require some experience or a guide because you won’t find stairs, rails, or lighting. With that said, some caves do handle tourists with comfort and safety measures implemented.

Why Are There So Many Caves in Montana? 

Most of the caves in Montana result from something called karst topography. This is when the soft bedrock, composed of mainly limestone, has been eroded over a great time by rains.

The water makes its way through the cracks and crevices in the rock, taking small limestone particles with it. Over many years — we’re talking millions of years — caves begin to appear where the rock once was.
